摘要
首次合成了镝和硫代脯氨酸、水杨酸的固体配合物,通过化学分析、元素分析、热重分析、红外光谱、摩尔电导等手段进行表征,确定其化学组成为[Dy(C7H5O3)2(C4H6NO2S)].2H2O.通过恒温环境溶解-反应量热法研究得到配合反应的标准反应焓为261.29±0.87kJmol-1,并计算配合物298.15K时的标准摩尔生成焓为-2780±3kJ.mol-1.
The novel ternary solid complex of Dysprosium chloride hexahydrate with salicylic acid and Thioproline, [Dy（C7H5O3）2（C4H7NO2S）]·2H2O, was synthesized and characterized by lit, elemental analysis, molar conductance, and thermogravimatric analysis. The enthalpy change of the reaction was determined to be △rH^⊙m = 261.29·0.87kJmol^-1. Using the relevant data in the literature, through Hess＇ law, the standard molar enthalpy of formation of [Dy（C7H5O3）2（C4H6NO2S）]·2H2O（s） was estimated to be △fH^⊙m [Dy（C7H5O3）2（C4H6NO2S）]·2H2O（s） ,298.15 K] = - 2780·3kJmol^-1 .
